Rewriting input as fractions if necessary:
9/10, 1/4
For the denominators (10, 4) the least common multiple (LCM) is 20.
LCM(10, 4)
Therefore, the least common denominator (LCD) is 20.
Calculations to rewrite the original inputs as equivalent fractions with the LCD:
9/10 = 9/10 × 2/2 = 18/20
1/4 = 1/4 × 5/5 = 5/20

Solve for x in the diagram below.
Answer:
x = 20
Step-by-step explanation:
The sum of the two angles is 90 degrees
x+3x+10 = 90
Combine like terms
4x+10 = 90
Subtract 10 from each side
4x+10-10 = 90-10
4x= 80
Divide each side by 4
4x/4 = 80/4
x = 20
Answer:
x = 20
Step-by-step explanation:
x and 3x + 10 form a right angle, then
x + 3x + 10 = 90
4x + 10 = 90 ( subtract 10 from both sides )
4x = 80 ( divide both sides by 4 )
x = 20
To find the total cost ( c ), substitute the value of (p) you just found, 285.7 , into one of the equations in the system
Answer:
c = 214.28 OR 214.275
Step-by-step explanation:
You could do c = 0.75(285.7) and you would get c = 214.275
Which of the following equations represents a line that passes through the points (10,9) and (0,-6)?
I. 3x-2y=12
II. y= 3/2x - 6
- - - - - - - - - - -
1- neither
2- I only
3- II only
4 - I and II only
Answer:
4
Step-by-step explanation:
I saw karma so i came as fast as I could- welp anyways
Lets test the first equation and coordinate #1 first, 3x-2y=12, and (10,9).
Here we can substitute x as 10 and y as 9, and solve the equation to see if 3(10)-2(9) equals 12 or not.
30-18=12, yep
now lets test the second coordinate, (0, -6). Substitute x as 0 and y as -6, and solve the equation.
3(0)-2(-6)=12
0+12=12, yep
So I definitely works
For II, lets do the same thing
(10, 9) -- 9=3/2*10-6
9=15-6, works
(0, -6) — -6= 3/2*0-6
-6=0-6, also works
So uh therefore I and II both work you see what I mean-
i apologize in advance if i made you more confused than you already are-

Traveon is walking dogs for his neighbors, to make money. This week, he walked Mr. Jackson's dog 3.5 times farther than he walk Ms. Evans' dog. If the total distance that he walked both dogs is 17.5 miles, how far did he walk Ms. Evans' dog? *
Answer:
He walked Ms. Evans' dog 3.89 miles.
Step-by-step explanation:
From the information provided, you know that the total distance that he walked both dogs is 17.5 miles, which can be expressed as:
x+y=17.5, where:
x is the distance he walked Mr. Jackson's dog
y is the distance he walked Ms. Evans' dog
Also, the statement indicates that he walked Mr. Jackson's dog 3.5 times farther than he walk Ms. Evans' dog and you can write the following equation:
x=3.5y
Now, you can replace x=3.5y in the first formula and solve for y to find how far he walked Ms. Evans' dog:
3.5y+y=17.5
4.5y=17.5
y=17.5/4.5
y=3.89
According to this, the answer is that he walked Ms. Evans' dog 3.89 miles.

Find the measures of the numbered angles in rhombus ABCD.
Answer:
∠1 = 66°
∠2 = 24°
∠3 = 24°
∠4 = 90°
Step-by-step explanation:
∠1 = 90 - 24 = 66°
∠2 = 24°
∠3 = 24° because segment DB bisects ∠ABC
∠4 = 90° because it is a right angle

Pls hurry will give BRAINLYEST Jillian wanted to determine the difference of 7 and a number, n. She wrote in a table several possible expressions she could use to represent this. Which is the correct expression number?
Expression Number
Expression

n minus 7
2
7 minus n
3
7 n
4
StartFraction n Over 7 EndFraction
Expression number:
To find the difference between two numbers you would subtract them.
You are told the first number is 7 and you want to find the different of 7 and a number, which is represented by the letter n.
To find the difference you would subtract n from 7, which would be written as 7 - n
The correct answer would be 2. 7 - n ( 7 minus n)
Answer: 7 - n (Look at the explanation to understand it clearly)
Normally you'll subtract this equation, but since there isn't a number but is a variable, you would have to rewrite it.
In this problem, we would represent n as the variable and 7 as the number. Rewrite it like this:
7 - n
Or you could say it like this:
A number decreased by 7.
"A number" would represent the variable.
Hence, your answer is 7 - n.

Answer:
5.65 hours
Step-by-step explanation:
Given: Initial number of bacteria = 1000
N=1000(2)
To find: Time taken to: increase to 50,000
Solution: N=1000(2)
50,000=1000(2)Taking log,log 50,000 = log 1000(2)4.7 = 3 + _ log 2_ = 1.7/log 2 = 5.65Answer = 5.65 hours

The number of bacteria in a petri dish is 50,000 (on day 0) if the amount is doubling each day by when will the number of bacteria be 400,000. Let x represent the number of days and f(x) represent the amount of bacteria. Write an equation.
Answer:
f(x) = 50000*2^x3 daysStep-by-step explanation:
Given:
Initial amount of bacteria = 50000Growth rate = 2 times a dayRequired equation:
f(x) = 50000*2^xSolve for x:
400000 = 50000*2^x2^x = 400000/500002^x = 82^x = 2^3x = 3After 3 days bacteria numbers will reach 400000
Robert bought a pair of shoes that was on sale for 30% off
the original price of $79.95. Which is closest to the sale
price of the pair of shoes?
Answer:
The sale price of the shoes is $55.96
Step-by-step explanation:
1: 30% of $79.95 is 23.985.
Which would round to $23.99.
Then subtract 23.99 from 79.95.
79.95-23.99= 55.96

A local shelter is having an Adopt-a-thon for kittens and puppies. Kittens cost $50 to adopt and puppies are $75. The shelter made $1200 during the Adopt-a-thon event and adopted off twice as many puppies as kittens. Write and solve a system to find how many puppies and kittens were adopted
Answer:
Step-by-step explanation:
P=2K
50K+75P=1200, using P from above makes this equation become
50K+75(2K)=1200
50K+150K=1200
200K=1200
K=6, since P=2K
P=2(6)=12
So 12 puppies and 6 kittens were adopted.
If – 2/3X – 1 = 4, then x =
Answer:
2/5
Step-by-step explanation:
The value of x will be x = -15/2
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
We are given that the equation – 2/3X – 1 = 4
Here, we need to solve for x,
– 2/3X – 1 = 4
Now combine the like terms;
– 2/3X = 4 + 1
-2/3x = 5
x = -15/2
Therefore, the solution will be as;
x = -15/2
The value of x will be; x = -15/2

Which value is a solution to the inequality x 4
Answer:
The answer is D
Step-by-step explanation:
We want to see which of the given values is a solution of the inequality:
x < 4
The correct option is A, x = 3.
Finding the solution:
So the inequality:
x < 4
This means that the variable must be a number smaller than 4.
Then we just need to select the option that is smaller than 4, the only option that meets this requirement is option A, x = 3
Also, as you can see in the number line, the only number that is in the shaded part is x = 3 (from the ones in the options).

Two angles are vertical if one is 5x - 15 and the second angle is 3x + 1, what is the value of x
What is the measure of each angle
Answer:
Step-by-step explanation:
If they are vertical angles, they are opposite to each other where two lines intersect. Vertical angles are equal to each other so
5x-15=3x+1
2x-15=1
2x=16
x=8 degrees.
The angles are
a=5x-15, and x=8 so
a=5(8)-15
a=40-15
a=25 degrees.
Mr. Torres bought 3 chairs on Saturday. He paid d dollars for each chair. Mr. Torres received $15 dollars in change when he bought the chairs. Which expression can be used to find the total amount Mr. Torres paid for these chairs
Answer: c. 3d + 15
Step-by-step explanation:
Mr. Torres paid d dollars for each of the three chairs which gives the expression of:
= 3 * d = 3d
He then paid with an amount that was greater than this 3d and got a change of $15.
That total amount that he paid is therefore, the price of the three chairs added to the $15 that he received back.
= 3d + 15
